Re: [Muine] muine database

[Jorn Baayen <jbaayen gnome org>]

Hey,

If you want to not batch load all cover images at once you'll have to
write your own loading code .. muine will always batch load so sharing
that code wouldn't make much sense .. basically all you need is db.c and
you need to know the db format.  The covers db format is not too likely
to change (but it might!), so you should be fine.  Detecting whether
muine is installed shouldnt be too hard, I mean, just check whether
~/.gnome2/muine/covers.db exists.

Having a library loading them into memory once would be more trouble
than it's worth, imho, and it would have a negative impact on muine's
performance. (Having to share the data through some IPC mechanism .. )

One random idea I got was that you could do something like this: See if
covers.db is there, if so, use it, and then check amazon for any missing
images or all images if covers.db doesn't exist.

HTH,

Jorn
